Approaches differ in the social tie definitions used to identify which social network members\u2019 abortion experiences respondents will report. This study compares the effect of using the \u201cbest friend\u201d (closest female friend) versus \u201cconfidante\u201d (specifying mutual sharing of personal information) definition on abortion incidence estimation. We use data from a nationally representative survey of women aged 15\u201349 in Burkina Faso (conducted in 2020\u20132021) where respondents were randomized into two versions of an abortion module, using different friend definitions. We computed abortion rate estimates by friend definition and adjusted for assumption violations (transmission bias, surrogate sample selection bias). Unadjusted incidence rates varied from 11.7 [4.1\u201319.2] abortions per 1,000 women to 15.6 [9.7\u201321.4], depending on friend definition. The confidante definition yielded higher adjusted estimates (36.2 [25.1\u201347.2]) than the best friend definition (17.0 [8.7\u201325.3]) due to greater transmission bias adjustment. Both estimates exceeded the respondent self\u2010reported abortion incidence (4.0 [2.2\u20135.9]). Our results indicate that either friend definition produces higher incidence estimates than self\u2010report but suggest a potential advantage for the \u201cbest friend\u201d over the \u201cconfidante\u201d definition given lower transmission bias. Further research should assess generalizability of these findings in other contexts.<\/jats:p>","DOI":"10.1111\/sifp.12213","type":"journal-article","created":{"date-parts":[[2022,10,10]],"date-time":"2022-10-10T11:37:53Z","timestamp":1665401873000},"page":"639-655","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Social Network\u2010Based Induced Abortion Incidence Estimation in Burkina Faso: Examining the Impact of the Network Generating Question"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7650-5940","authenticated-orcid":false,"given":"Suzanne O.","family":"Bell","sequence":"first","affiliation":[{"name":"Department of Population, Family and Reproductive Health Johns Hopkins Bloomberg School of Public Health  Baltimore MD 21205 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georges","family":"Guiella","sequence":"additional","affiliation":[{"name":"Institut Sup\u00e9rieur des Sciences de la Population (ISSP) Universit\u00e9 Joseph Ki\u2010Zerbo  Ouagadougou Burkina Faso"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5986-1858","authenticated-orcid":false,"given":"Selena","family":"Anjur\u2010Dietrich","sequence":"additional","affiliation":[{"name":"Department of Population, Family and Reproductive Health Johns Hopkins Bloomberg School of Public Health  Baltimore MD 21205 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fiacre","family":"Bazie","sequence":"additional","affiliation":[{"name":"Institut Sup\u00e9rieur des Sciences de la Population (ISSP) Universit\u00e9 Joseph Ki\u2010Zerbo  Ouagadougou Burkina Faso"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yentema","family":"Onadja","sequence":"additional","affiliation":[{"name":"Institut Sup\u00e9rieur des Sciences de la Population (ISSP) Universit\u00e9 Joseph Ki\u2010Zerbo  Ouagadougou Burkina Faso"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saifuddin","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Population, Family and Reproductive Health Johns Hopkins Bloomberg School of Public Health  Baltimore MD 21205 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Moreau","sequence":"additional","affiliation":[{"name":"Department of Population, Family and Reproductive Health Johns Hopkins Bloomberg School of Public Health  Baltimore MD 21205 USA"},{"name":"Soins Primaires et Pr\u00e9vention CESP Centre for Research in Epidemiology and Population Health  U1018, Inserm Villejuif F\u201094800 France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,10,9]]},"reference":[{"issue":"1","key":"e_1_2_10_2_1","first-page":"1","article-title":"Induced Abortion Incidence and Safety in Rajasthan, India: Evidence that Expansion of Services is Needed","volume":"18","author":"Ahmad Danish","year":"2020","journal-title":"Studies in Family Planning"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjgh-2021-007151"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/padr.12403"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjgh\u20102019\u2010001814"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12963-020-00235-y"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0232364"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph16224425"},{"key":"e_1_2_10_9_1","unstructured":"Elul Batya.2004. \"Anonymous Third Party Reporting of Induced Abortion: An Experiment in Rajasthan India.\" Paper presented atAnnual Meeting of the Population Association of America Boston MA April 1\u20133."},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/0081175016665425"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1086\/209351"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/sifp.12180"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1353\/dem.2006.0024"},{"key":"e_1_2_10_14_1","volume-title":"Enqu\u00eate sur les indicateurs du paludisme au Burkina Faso, 2017\u20102018","author":"Institut National de la Statistique et de la D\u00e9mographie (INSD), Programme d'Appui au D\u00e9veloppement Sanitaire (PADS), Programme National de Lutte contre le Paludisme (PNLP), and ICF","year":"2018"},{"key":"e_1_2_10_15_1","volume-title":"Enqu\u00eate D\u00e9mographique et de Sant\u00e9 et \u00e0 Indicateurs Multiples du Burkina Faso 2010","author":"Institut National de la Statistique et de la D\u00e9mographie (INSD) et ICF International","year":"2012"},{"key":"e_1_2_10_16_1","unstructured":"Institut Sup\u00e9rieur des Sciences de la Population Universit\u00e9 Joseph Ki\u2010Zerbo Ouagadougou Burkina Faso;
